Welcome to the Ma Lab!

We are part of the Lombardi Comprehensive Cancer Center in the Medical Center at the Georgetown University.

Dr. Junfeng Ma’s research team is mainly focused on the study of proteins and their post-translational modifications (PTMs) in physiology and pathology. We are very interested in the characterization of protein glycosylation, especially O-linked β-N-acetylglucosamine (O-GlcNAc) modification (i.e., O-GlcNAcylation), by using multidisciplinary approaches. Specifically, we are devoted to 1) developing novel chromatographic and mass spectrometric methods for precision proteomics and 2) exploring the functional roles of protein O-GlcNAcylation in diseases by using a variety of methods including proteomics, biochemistry and molecular biology techniques.

Besides basic research, we look forward to conducting translational research for the discovery of new biomarkers and therapeutics for precision medicine.

We are open to collaborate with national and international investigators to answer biomedical questions of interest!
